If your garden holds water after rain or your patio keeps puddling, our team can help. We provide surface drainage, land drains and gutter drainage solutions across KT3, including around New Malden High Street and Beverley Park. Every design is tailored to how water moves through your plot, not a one-size-fits-all trench. The aim is simple: move water away from buildings and restore usable outdoor space.
New Malden’s mix of 1930s semis, Edwardian houses and modern apartments often comes with different drainage challenges. Older homes may have tired clay pipes, settled patios and narrow side access, while newer blocks can suffer from overwhelmed surface runs and poorly directed downpipes. We regularly work in the drainage contractors New Malden area including Raynes Park, Motspur Park and Worcester Park. That local variety helps us specify the right gradients, pipe sizes and discharge points first time.
We start with a clear site assessment and, where needed, CCTV surveys to locate breaks, silt build-up or root ingress. Then we propose the most effective option—French drains, soakaways, channel drains or a combination—explaining depths, falls and where the water will go. Our installations are neat, with careful reinstatement of lawns, paving and borders. Homeowners choose us for straightforward communication, tidy working and a 10-year warranty on qualifying installations.
We’re used to the access and parking realities around Manor Park and the busier stretches near New Malden High Street, so we plan deliveries and spoil removal carefully. Ground conditions can vary from compacted garden soils to made-up ground around extensions, which affects soakaway performance and trench stability. We also account for tight side passages typical of 1930s semis, choosing methods that reduce disruption. As drainage contractors in Royal Borough of Kingston upon Thames, we work with practical, compliant outfalls and sensible reinstatement.

Costs depend on the cause and the solution. A CCTV survey is often £180–£350. Small surface drainage or a short channel drain run can be £600–£1,500. French drains typically range from £1,500–£4,500 depending on length and reinstatement. Soakaways are commonly £1,800–£5,500, influenced by soil type, crate size, access and whether excavation and spoil removal are difficult in KT3.
Many jobs are completed in 1–3 days, such as a channel drain along a patio edge or a short French drain run. Larger schemes—multiple land drains, a new soakaway and rerouted gutter drainage—often take 3–7 days. Timescales depend on access, depth, ground conditions, weather, and how much paving or lawn needs lifting and reinstating. CCTV surveys are usually done within a couple of hours on site.
Most garden drainage improvements, such as French drains, land drains and replacing gutter connections, are permitted and don’t require planning permission. However, rules can change if you’re altering levels significantly, working near boundaries, affecting a shared drain, or discharging into a public sewer. If your property is listed or in a sensitive area, extra checks may apply. We’ll advise on the safest compliant approach before work starts.
We provide a 10-year warranty on qualifying drainage installations, covering workmanship and the performance of installed components when used as designed. This includes correctly installed French drains, soakaway systems, channel drains and connected pipework. The warranty doesn’t cover damage from third-party works, misuse, or extreme events beyond design assumptions, but we’ll always help diagnose issues quickly. You’ll also receive clear maintenance guidance to keep systems flowing freely.
We can install perforated land drain pipe in gravel trenches, modular soakaway crates with geotextile wrap, and surface channel drains in polymer concrete or uPVC with galvanised or stainless grates. For patios and driveways, we’ll advise on discreet linear drains and silt traps to reduce blockages. Gutter drainage can be upgraded with new underground runs and rodding access points. We help you choose based on soil, fall, aesthetics and budget.
